After saving all your settings, you want to go through and check them to make sure they are what you wanted. Go to one of the pages where you modified the elements and look to see if your new settings are in place. If for some reason your settings aren’t changed, it could be due to your caching. When that happens, you simply need to clear the cache.
To clear the cache, go to the configuration->performance (which is under the development heading)
From there, click the “Clear all caches” button.
